The 27-year-old singer played the proud boyfriend by sharing a photo from Gomez's newly-released Coach campaign Wednesday on Instagram Stories.
The Weeknd chose a sultry shot of Gomez reclining in the backseat of a car with a fur coat and leather bag. He captioned the image with five diamond emojis.
Gomez herself bragged about The Weeknd on Instagram Stories this month after the singer appeared on the cover of Forbes. She also shows her support for the recording artist by attending his concerts.
"I love being supportive," the star said on the June 5 episode of SirirusXM's The Morning Mashup. "I love just being there and just kind of having somebody's back. It feels good. I haven't had that feeling in a while."
The Weeknd and Gomez were first linked in January, and made their red carpet debut as a couple at the Met gala in May. Gomez recently said she went public with The Weeknd because she's happy and uninhibited with the singer.
"I'm so happy with my music, my health is most important, my family is most important, but at the same time I just want to be happy. So if that's me just being myself, then I really don't care," she explained.
